TPA3116D2DADR

TPA3116D2DADR is the tape-and-reel HTSSOP-32 ordering code for the Texas Instruments TPA3116D2 stereo Class-D audio amplifier, listed as ACTIVE. Verified figures: a supply of 4.5 V to 26 V, and — at TA = 25 °C — a typical output power of 50 W per channel in BTL at PVCC = 21 V, RL = 4 Ω, f = 1 kHz and THD+N = 10 %, with THD+N of 0.1 % typical at the same voltage, load, frequency and temperature at the 25 W half-power point; an RDS(on) of 0.12 Ω and efficiency above 90 %. The selection point is amplifier power per board area: a stereo 100 W-class output stage in one PowerPAD package, with the reel packing denoted by the R at the end of the code matched to automated assembly — the tube-packed TPA3116D2DAD also listed in this catalog is the same device in prototype-friendly packing. Selection advice: the 50 W per channel figure is a BTL figure at 21 V into 4 Ω taken at 10 % distortion — it is not a 50 W at 0.1 % point; the 0.1 % figure belongs to half power. A single-ended or 12 V design delivers a fraction of either, so size the supply and the heatsinking to your actual rail and load rather than the headline wattage.
